Environmental Protection Agency (EPA).


Proposed rule.


Under the Federal Clean Air Act (CAA), the Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) submission from the Governor of New Mexico for the City of Albuquerque-Bernalillo County for the 2008 Lead (Pb) National Ambient Air Quality Standards (NAAQS). The submittal addresses how the existing SIP provides for implementation, maintenance, and enforcement of the 2008 Pb NAAQS (infrastructure SIP or i-SIP). This i-SIP ensures that the State's SIP for Albuquerque-Bernalillo County is adequate to meet the state's responsibilities under the CAA, including the four CAA requirements for interstate transport of Pb emissions.

I. Background

On October 5, 1978, we published the first NAAQS for lead (Pb) (43 FR 46246). Both the primary and secondary standards were set at 1.5 micrograms per cubic meter (µg/m3). In 2008, following a periodic review of the NAAQS for lead, we published a revised, more stringent NAAQS of 0.15 µg/m3 for both the primary and secondary standards (73 FR 66964, November 13, 2008). For more information on these standards, please see the Technical Support Document (TSD) and EPA Web site​airquality/​lead.

Each state must submit an i-SIP within three years after the promulgation of a new or revised NAAQS. Section 110(a)(2) of the CAA includes a list of specific elements the i-SIP must meet. EPA issued guidance addressing the i-SIP elements for NAAQS.[1] The Governor of New Mexico on behalf of Albuquerque-Bernalillo County submitted an i-SIP revision on May 2, 2012 to address this revised NAAQS, including a demonstration that the SIP met the four statutory requirements for interstate transport of Pb emissions.

EPA is proposing to approve the Albuquerque-Bernalillo County, New Mexico i-SIP submittal for the 2008 Pb NAAQS [2] as meeting the requirements Start Printed Page 54740for an i-SIP, including the requirements for interstate transport of Pb emissions

II. EPA's Evaluation of New Mexico's i-SIP and Interstate Transport Submittal

Below is a summary of EPA's evaluation of the Albuquerque-Bernalillo County, New Mexico i-SIP for each applicable element of 110(a)(2) A-M. The Albuquerque-Bernalillo County Air Quality Control Board (Air Board) provided a demonstration of how the existing Albuquerque-Bernalillo County, New Mexico SIP met all the requirements of the 2008 Pb NAAQS on May 2, 2012. This SIP submission became complete by operation of law on November 2, 2013. See CAA section 110(k)(1)(B).

(A) Emission limits and other control measures: The SIP must include enforceable emission limits and other control measures, means or techniques, schedules for compliance and other related matters as needed to implement, maintain and enforce each of the NAAQS.[3]

Legislative authority for Albuquerque-Bernalillo County's air quality program, codified in Chapter 74 Environmental Improvement, Article 2, Air Pollution, of the New Mexico statutes, gives the Air Board and the Albuquerque Environmental Health Department's Air Quality Program (AQP) the authority to implement the CAA in Albuquerque-Bernalillo County, New Mexico. Enforceable emission limitations and other control measures are authorized by the New Mexico Air Quality Control Act (AQCA) which established the Air Board and those provisions of New Mexico Administrative Code (NMAC) Title 20, Environmental Protection, Chapter 11, Albuquerque-Bernalillo County Air Quality Control Board. They can adopt emission standards and compliance schedules applicable to regulated entities; emission standards and limitations and any other measures necessary for attainment and maintenance of national standards; and, enforce applicable laws, regulations, standards and compliance schedules, and seek injunctive relief within the boundaries of Bernalillo County. This authority has been employed to adopt and submit multiple revisions to the Albuquerque-Bernalillo County, New Mexico State Implementation Plan. The approved SIP for Albuquerque-Bernalillo County, New Mexico is documented at 40 CFR 52.1620, Subpart GG.

(B) Ambient air quality monitoring/data system: The SIP must provide for establishment and implementation of ambient air quality monitors, collection and analysis of monitoring data, and providing the data to EPA upon request.

The AQCA provides AQP with the authority to monitor ambient air quality in the county (NMSA 1978, section 74-2-5). AQP maintains a monitoring network for the NAAQS and submits an annual Network Assessment to EPA. The network includes one monitor for Pb. AQP's 2014 Air Monitoring Network Plan is the most recently EPA-approved network monitoring plan and was approved by EPA on February 3, 2015. All monitoring data is measured using EPA approved methods and subject to the EPA quality assurance requirements. AQP submits all required data to EPA, in accordance with EPA rules. The monitoring network was approved into the SIP (46 FR 4005, August 6, 1981). AQP conducts an assessment of the monitoring network every 5 years. Data is available upon request and in the EPA Air Quality System (AQS) database.

(C) Program for enforcement. The SIP must include the following three elements: (1) A program providing for enforcement of the measure in paragraph A above; (2) a program for the regulation of the modification and construction of stationary sources as necessary to protect the applicable NAAQS (i.e., state-wide permitting of minor sources); and (3) a permit program to meet the major source permitting requirements of the CAA (for areas designated as attainment or unclassifiable for the NAAQS in question).[4]

(1) Enforcement of SIP Measures. As noted in (A), the state statutes provide authority for the AQP to enforce the requirements of the AQCA within Albuquerque-Bernalillo County, and any regulations, permits, or final compliance orders. Its statutes also provide the AQP with general enforcement powers. Among other things, they can file lawsuits to compel compliance with the statutes and regulations; commence civil actions; issue field citations; conduct investigations of regulated entities; collect criminal and civil penalties; develop and enforce rules and standards related to protection of air quality; issue compliance orders; pursue criminal prosecutions; investigate, enter into remediation agreements; and issue emergency cease and desist orders. The AQAC also provides additional enforcement authorities and funding mechanisms.

(2) Minor New Source Review (NSR). The SIP is required to include measures to regulate construction and modification of stationary sources to protect the NAAQS. Albuquerque-Bernalillo County's minor NSR permitting requirements are approved as part of the SIP.[5]

(3) Prevention of Significant Deterioration (PSD) permit program. Albuquerque-Bernalillo County's PSD portion of the SIP covers all NSR regulated pollutants as well as the requirements for the 2008 Pb NAAQS and has been approved by EPA.[6] In a recent action, EPA approved revisions that address the requirements of the EPA's May 2008, July 2010, and October 2012 PM2.5 PSD Implementation Rules and to incorporate revisions consistent with the EPA's March 2011 Fugitives Interim Rule, July 2011 Greenhouse Gas (GHG) Biomass Deferral Rule, and July 2012 GHG Tailoring Rule Step 3 and GHG PALs Rule (see docket EPA-R06-OAR-2013-0616 in

(D) Interstate and international transport: The requirements for interstate transport of Pb emissions are that the SIP contain adequate provisions prohibiting Pb emissions to other states which will (1) contribute significantly to nonattainment of the NAAQS, (2) interfere with maintenance of the NAAQS, (3) interfere with measures required to prevent significant Start Printed Page 54741deterioration or (4) interfere with measures to protect visibility (CAA 110(a)(2)(D)(i)).

With respect to significant contribution to nonattainment or interference with maintenance of the Pb NAAQS, the physical properties of Pb, which is a metal and very dense, prevent Pb emissions from experiencing a significant degree of travel in the ambient air. No complex chemistry is needed to form Pb or Pb compounds in the ambient air; therefore, ambient concentrations of Pb are typically highest near Pb sources. More specifically, there is a sharp decrease in ambient Pb concentrations as the distance from the source increases. According to EPA's report entitled Our Nation's Air: Status and Trends Through 2010, Pb concentrations that are not near a source of Pb are approximately 8 times less than the typical concentrations near the source.[7] For these reasons, EPA believes that the interstate transport requirements pertaining to significant contribution to nonattainment or interference with maintenance of the Pb NAAQS can be satisfied through a state's assessment as to whether a lead source located within its state in close proximity to a state border has emissions that contribute significantly to the nonattainment in or interfere with maintenance of the NAAQS in the neighboring state. Albuquerque-Bernalillo County has stated as such in its submission.

There are no areas within Albuquerque-Bernalillo County that are designated as nonattainment with respect to the 2008 Pb NAAQS, and there are no significant sources of Pb emissions within the County that emit Pb in amounts equal to or exceeding 0.5 tons per year, nor sources of Pb emissions within two miles of a neighboring state line. Total Pb emissions within Albuquerque-Bernalillo County in 2011 were less than two tons, and most of the Pb-emitting sources within the State are general aviation airports where aviation gasoline containing tetra-ethyl lead is still in use. Therefore, we deem that Albuquerque-Bernalillo County has presumptively satisfied the interstate transport requirements pertaining to significant contribution to nonattainment or interference with maintenance of the Pb NAAQS.

With respect to the interstate transport and PSD requirement, we note that Albuquerque-Bernalillo County's satisfaction of the applicable infrastructure SIP PSD requirements for attainment/unclassifiable areas with regards to the 2008 Pb NAAQS have been detailed in the section addressing section 110(a)(2)(C). Therefore, we deem that the SIP has presumptively satisfied the interstate transport and PSD requirement.

With regard to the applicable requirement for interstate transport and visibility protection, significant impacts from Pb emissions from stationary sources are expected to be limited to short distances from the source and most, if not all, stationary sources of Pb emissions are located at sufficient distances from Class I areas such that visibility impacts would be negligible. Although Pb can be a component of coarse and fine particles, Pb generally comprises only a small fraction of coarse and fine particles. A recent EPA study conducted to evaluate the extent that Pb could impact visibility concluded that Pb-related visibility impacts at Class I areas were found to be insignificant (e.g., less than 0.10%).[8] Given this information, that there are no significant point sources of Pb emissions and that the County is not near an interstate border we deem the SIP meets the interstate transport and visibility protection.

Section 110(a)(2)(D)(ii) also requires that the SIP ensure compliance with the applicable requirements of sections 126 and 115 of the CAA, relating to interstate and international pollution abatement, respectively. Section 126(a) of the CAA requires new or modified sources to notify neighboring states of potential impacts from sources within the State. Albuquerque-Bernalillo County regulations require that affected states, tribes and federal land managers receive notice prior to the commencement of any construction or significant modification of a major source. In addition, no source or sources located in Albuquerque-Bernalillo County have been identified by EPA as having any interstate impacts under section 126 in any pending actions relating to any air pollutant.

Section 115 of the CAA authorizes EPA to require a state to revise its SIP under certain conditions to alleviate international transport into another country. There are no final findings under section 115 of the CAA against New Mexico with respect to any air pollutant. Thus, the State's SIP does not need to include any provisions to meet the requirements of section 115.

Based upon review of the State's infrastructure SIP submission for the 2008 Pb NAAQS, and relevant statutory and regulatory authorities and provisions referenced in the submission or referenced in New Mexico's SIP, EPA believes that Albuquerque-Bernalillo County has the adequate infrastructure needed to address sections 110(a)(2)(D)(i)(I) and (II) (all 4 interstate transport requirements), and 110(a)(2)(D)(ii) for the 2008 Pb NAAQS and is proposing to approve this element of the May 2, 2012, submission.

(E) Adequate authority, resources, implementation, and oversight: The SIP must provide for the following: (1) Necessary assurances that the state (and other entities within the state responsible for implementing the SIP) will have adequate personnel, funding, and authority under state or local law to implement the SIP, and that there are no legal impediments to such implementation; (2) requirements relating to state boards; and (3) necessary assurances that the state has responsibility for ensuring adequate implementation of any plan provision for which it relies on local governments or other entities to carry out that portion of the plan.

Both elements A and E address the requirement that there is adequate authority to implement and enforce the SIP and that there are no legal impediments.

This i-SIP submission for the 2008 Pb NAAQS describes the SIP regulations governing the various functions of personnel within the AQP and the Air Board, including the administrative, technical support, planning, enforcement, and permitting functions of the program.

With respect to funding, the resources to carry out the plan are provided through General Funds, Permit Fees and the CAA grant process. Permit Fees are collected under the authority of section 74-2-7.

As required by the CAA and the Environmental Improvement Act (EIA), the SIP stipulates that any members of the board or body, or the head of an agency with similar powers, adequately disclose any potential conflicts of interest. NMSA 1978 section 74-1-4 provides the Air Board contain at least a majority of members who represent the public interest and do not derive any significant portion of their income from persons subject to or who appear before the board on issues related to the CAA or the Air Act. Board members are required to recuse themselves from rule-makings in which their impartiality may reasonably be questioned.

With respect to assurances that the Air Board has responsibility to implement the SIP adequately when it Start Printed Page 54742authorizes local or other agencies to carry out portions of the plan, the EIA and the AQCA designate the Air Board as the primary air pollution control agency within Albuquerque-Bernalillo County. The statutes allow for local agencies to carry out some or all of the Act's responsibilities.

The Albuquerque-Bernalillo County Air Quality Control Board assumes jurisdiction for local administration and enforcement of the AQCA in Bernalillo County. There are Albuquerque/Bernalillo County SIP provisions which are part of the New Mexico SIP.[9]

(F) Stationary source monitoring system: The SIP requires the establishment of a system to monitor emissions from stationary sources and to submit periodic emission reports. It must require the installation, maintenance, and replacement of equipment, and the implementation of other necessary steps, by owners or operators of stationary sources, to monitor emissions from sources. The SIP shall also require periodic reports on the nature and amounts of emissions and emissions-related data from sources, and require that the state correlate the source reports with emission limitations or standards established under the CAA. These reports must be made available for public inspection at reasonable times.

Requirements in 20.11.47 NMAC, Emission Inventory Requirements provide for the reporting of emissions inventories in a format established by AQP on a schedule prescribed by the regulation. There also are SIP state regulations pertaining to sampling and testing and requirements for reporting of emissions inventories. In addition, SIP rules establish general requirements for maintaining records and reporting emissions. This information is used to track progress towards measuring the NAAQS, developing control and maintenance strategies, identifying sources and general emission levels, and determining compliance with SIP regulations and additional EPA requirements.

(G) Emergency authority: The SIP must provide for authority to address activities causing imminent and substantial endangerment to public health or welfare or the environment and to include contingency plans to implement such authorities as necessary.

The AQCA provides the New Mexico Environment Department with authority to address environmental emergencies, inclusive of contingency plans to implement emergency episode provisions.

Pursuant to 40 CFR 51, Subpart H, Prevention of Air Pollution Emergency Episodes, on January 26, 1989, the Air Board adopted the Air Pollution Contingency Plan for Bernalillo County [8/21/91, 56 FR 38074; 40 CFR 52.1639, Prevention of Air Emergency Episodes], which is part of the SIP, which covers air pollution episodes and the occurrence of an emergency due to the effects of the pollutants on the health of persons.

(H) Future SIP revisions: States must have the authority to revise their SIPs in response to changes in the NAAQS, availability of improved methods for attaining the NAAQS, or in response to an EPA finding that the SIP is substantially inadequate to attain the NAAQS.

Albuquerque-Bernalillo County's SIP is a compilation of regulations, plans and submittals that act to improve and maintain air quality in accordance with national standards. The authority to develop or revise the SIP is based on the authority to adopt new regulations and revise existing regulations to meet the NAAQS. NMSA 1978 section 74-7-5 gives the board the authority to perform these functions. Section 74-7-5 also gives the board the authority to adopt regulations to abate, control and prohibit air pollution throughout Albuquerque-Bernalillo County in accordance with the State Rules Act. Nothing in New Mexico's statutory or regulatory authority prohibits Albuquerque-Bernalillo County from revising the SIP in the event of a revision to the NAAQS. The AQCA specifically requires revisions to the SIP if the scenarios set forth in Section 110(a)(2)(H) occur.

(I) Nonattainment areas: The CAA section 110(a)(2)(I) requires that in the case of a plan or plan revision for areas designated as nonattainment areas, states must meet applicable requirements of part D of the CAA, relating to SIP requirements for designated nonattainment areas.

As noted earlier, EPA does not expect infrastructure SIP submissions to address subsection (I). The specific SIP submissions for designated nonattainment areas, as required under CAA title I, part D, are subject to different submission schedules than those for section 110 infrastructure elements. Instead, EPA will take action on part D attainment plan SIP submissions through a separate rulemaking process governed by the requirements for nonattainment areas, as described in part D. The Albuquerque-Bernalillo County nonattainment new source review (NNSR) provisions required for the 2008 Pb NAAQS and other NAAQS were approved as part of the SIP (72 FR 20728, April 26, 2007).

Additionally, Albuquerque-Bernalillo County presently does not contain any non-attainment areas for Pb.

(J) Consultation with government officials, public notification, PSD and visibility protection: The SIP must meet the following three requirements: (1) Relating to interagency consultation regarding certain CAA requirements; (2) relating to public notification of NAAQS exceedances and related issues; and, (3) prevention of significant deterioration of air quality and visibility protection.

(1) Interagency consultation: As required by the AQCA, there must be a public hearing before the adoption of any regulations or emission control requirements and all interested persons must be given a reasonable opportunity to submit data, view documents, or argue orally or in writing and to examine testimony of witnesses from the hearing. In addition, the AQAC provides for the power and duty to “advise, consult, contract with and cooperate with local authorities, other states, the federal government and other interested persons or groups in regard to matters of common interest in the field of air quality control . . . ”. Furthermore, New Mexico's PSD SIP rules mandate public participation and notification regarding permitting applications to any other state or local air pollution control agencies, local government officials of the city or county where the source will be located, tribal authorities, and Federal Land Managers (FLMs) whose lands may be affected by emissions from the source or modification. The State's Transportation Conformity SIP rules also provide procedures for interagency consultation, resolution of conflicts, and public notification.

(2) Public Notification: The i-SIP provides the SIP regulatory citations requiring the Air Board to regularly notify the public of instances or areas in which any NAAQS are exceeded, advise the public of the health hazard associated with such exceedances, and enhance public awareness of measures that can prevent such exceedances and ways in which the public can participate in efforts to improve air quality. 20.11.82 NMAC, Rulemaking Procedures—Air Quality Board, stipulates notice requirements for rulemaking and is used as a guide for notice requirements when adopting SIPs.Start Printed Page 54743

(3) PSD and Visibility Protection: The PSD requirements here are the same as those addressed under (C). The Albuquerque-Bernalillo County, New Mexico SIP requirements relating to visibility and regional haze are not affected when EPA establishes or revises a NAAQS. Therefore, EPA believes that there are no new visibility protection requirements due to the revision of the NAAQS, and consequently there are no newly applicable visibility protection obligations pursuant to infrastructure element J after the promulgation of a new or revised NAAQS.

(K) Air quality and modeling/data: The SIP must provide for performing air quality modeling, as prescribed by EPA, to predict the effects on ambient air quality of any emissions of any NAAQS pollutant, and for submission of such data to EPA upon request.

AQP has the duty, authority and technical capability to conduct air quality modeling, pursuant to the AQCA, in order to assess the effect on ambient air quality of relevant pollutant emissions; and can provide relevant data as part of the permitting and NAAQS implementation process. AQP follows EPA guidelines for air dispersion modeling. Upon request, AQP will submit current and future data relating to air quality modeling to EPA.

(L) Permitting Fees: The SIP must require each major stationary source to pay permitting fees to the permitting authority, as a condition of any permit required under the CAA, to cover the cost of reviewing and acting upon any application for such a permit, and, if the permit is issued, the costs of implementing and enforcing the terms of the permit. The fee requirement applies until a fee program established by the state pursuant to title V of the CAA, relating to operating permits, is approved by EPA.

The fee requirements of 20.11.2 NMAC have been approved by EPA as meeting the CAA requirements and were incorporated into the Albuquerque-Bernalillo County, New Mexico SIP [4/10/80, 45 FR 24468]. Albuquerque-Bernalillo County's title V operating permit program codified at 20.11.42 NMAC, Operating Permits, was approved by EPA on 9/8/04 [FR vol. 69, No. 173, pp. 54244-47]. In addition, see element (E) above for the description of the mandatory collection of permitting fees outlined in the SIP.

(M) Consultation/participation by affected local entities: The SIP must provide for consultation and participation by local political subdivisions affected by the SIP.

New Mexico State Statute Section 74-2-5.2 State Air Pollution Control Agency; Specific Duties and Powers of the Department, states that, “The department is the state air pollution control agency for all purposes under federal legislation relating to pollution. The department is required to “advise, consult, contract and cooperate with local authorities, other states, the federal government and other interested persons or groups in regard to matters of common interest in the field of air quality control.” Also see element (J) above for a discussion of the SIP's public participation process, the authority to advise and consult, and the PSD SIP's public participation requirements.

III. Proposed Action

EPA is proposing to approve the May 2, 2012, infrastructure SIP submission from Albuquerque-Bernalillo County, New Mexico, which addresses the requirements of CAA sections 110(a)(1) and (2) as applicable to the 2008 Pb NAAQS. Specifically, EPA is proposing to approve the following infrastructure elements: 110(a)(2)(A), (B), (C), (D), (E), (F), (G), (H), (J), (K), (L), and (M). EPA is not proposing action pertaining to section 110(a)(2)(I)—Nonattainment Area Plan or Plan Revisions as EPA believes this need not be addressed in the i-SIP. Based upon review of the state's infrastructure SIP submissions and relevant statutory and regulatory authorities and provisions referenced in these submissions or referenced in Albuquerque-Bernalillo County, New Mexico's SIP, EPA believes that Albuquerque-Bernalillo County, New Mexico has the infrastructure in place to address all applicable required elements of sections 110(a)(1) and (2) to ensure that the 2008 Pb NAAQS are implemented in the county. We also are proposing to approve the State's demonstration that it meets the four statutory requirements for interstate transport of Pb emissions.

IV. Statutory and Executive Order Reviews

Under the Clean Air Act, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the CAA. Accordingly, this action merely proposes to approve state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this action:

  • Is not a “significant regulatory action” subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993);
  • Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
  • Is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.);
  • Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4);
  • Does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);
  • Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);
  • Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001);
  • Is not subject to requirements of Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the CAA; and
  • Does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994).

In addition, the SIP is not approved to apply on any Indian reservation land or in any other area where EPA or an Indian tribe has demonstrated that a tribe has jurisdiction. In those areas of Indian country, the proposed rule does not have tribal implications and will not impose substantial direct costs on tribal governments or preempt tribal law as specified by Executive Order 13175 (65 FR 67249, November 9, 2000).

3.  The specific nonattainment area plan requirements of section 110(a)(2)(I) are subject to the timing requirements of section 172, not the timing requirement of section 110(a)(1). Thus, section 110(a)(2)(A) does not require that states submit regulations or emissions limits specifically for attaining the 2008 Pb NAAQS. Those SIP provisions are due as part of each state's attainment plan, and will be addressed separately from the requirements of section 110(a)(2)(A). In the context of an infrastructure SIP, EPA is not evaluating the existing SIP provisions for this purpose. Instead, EPA is only evaluating whether the state's SIP has basic structural provisions for the implementation of the NAAQS.

EPA believes that a number of states may have minor NSR provisions that are contrary to the existing EPA regulations for this program. The statutory requirements of section 110(a)(2)(C) provide for considerable flexibility in designing minor NSR programs.
